USB Digital I/O USB-DIO24, -1024, and -DIO96H Series Features • 24 digital I/O (USB-DIO24 Series and USB-1024 Series) or 96 digital I/O (USB-DIO96H Series) • High current output available • Event counter available USB-DIO24 Series boards (left) provide 24 DIO. The USB-1024 Series (middle) provide the same functionality as the USB-DIO24 Series and are shipped in a case. USB-DIO96H Series (right) provide 96 DIO, high-drive current output and are shipped in a metal enclosure. • Available as board-only (USB‑DIO24 Series), enclosed in a housing (USB-DIO96H Series), or cased (USB-1024 Series) Supported Operating Systems • Windows® 11/10/8/7/Vista®/ The USB-DIO24, -1024, and -DIO96H Series are digital I/O data acquisition devices. The USB-1024 Series adds 24 lines of logic-level digital I/O to any USB port. The USB-1024HLS high output current can drive many logic level devices directly, eliminating the need for costly buffer circuitry. The USB-DIO24 Series has all the functionality of the USB-1024 Series, but is enclosed in a case and designed with a D connector that matches the PCI-DIO24, making it easy to replace PCI boards in your applications. The USB-DIO96H Series provides 96 lines of high-current, logic-level, bidirectional digital I/O. The units offer 4 independent 24-bit DIO groups, each divided into two 8-bit ports and two 4-bit ports. The outputs can drive a wide assortment of external devices directly, without additional buffering. USB-DIO96H Series are housed in a heavy-duty chassis with integrated mounting slots. Digital I/O USB-DIO24 Series and USB-1024 Series USB-DIO24 and USB-1024 Series provide 24 DIO channels configured as either two banks of eight ports and two banks of four ports, or three banks of eight ports. Each port is independently configurable for input or output. The USB-DIO24/37 and USB-1024LS are designed with an 82C55 interface chip. The USB-DIO24H/37 and USB-1024HLS are designed to emulate 82C55 mode 0. Outputs are high-drive TTL that can source 15 mA and sink 64 mA. Digital I/O lines are accessed through a 37-pin D-type connector on the USB-DIO24 Series, and through screw terminals on the USB-1024 Series. USBDIO24 Series are board-only, while the USB-1024 Series are shipped in a case. The USB-DIO96H Series provides 96 DIO channels that are configured as eight banks of eight ports and eight banks of four ports. Each port is independently configurable for input or output. USBDIO96H Series devices are designed to emulate 82C55 mode 0. Digital outputs are high-drive TTL that can source 24 mA/sink 64 mA. Digital I/O lines are accessed through the screw terminals on the USB-DIO96H, and through the header connectors on the USB-DIO96H/50. USB-DIO96H Series boards are shipped in a rugged metal enclosure that you can mount on a DIN rail or bench.

USB Digital I/O Ordering Data Transfer Rates Sink current: 64 mA per output max Power-up state: Input mode Debounce mode (available through firmware): samples all inputs eight times over a specified interval, and latches out the input state when eight consecutive samples are identical (all 0 or all 1). Debouncing intervals: 1 ms, 2 ms, 5 ms, 10 ms, 20 ms, 50 ms, 100 ms, 200 ms, and 400 ms. Debounce interval accuracy: +0% / –12.5% Note: The board revision may be determined from the part number label on the housing that states “193770X-01L”, where X is the board revision.
